This means consists of toothed wheels 11 The-turning of the ladies to' "discharge the glass-and to bring it to the 1 as setforth in applicat-ion'Serial'No; 67 S,0t1. i After the molds have'been discharged they secured on the ladle shafts 2 and a series of "pins 12 secured to a stationary part of the with its laddle will reach the posit-ion described before another ladle, the carriage of apparatus at the points where the ladle is to In order to hold the ladies in the different positions to which-they are" ac turned.

shifted disks l3 provided with notches in their peripheries fastened on theladle shafts and spring actuated dogs 1 1 are so mounted. on the slides las to engage the notches in the disks. p n

From the lower frame the carriages 5 carrying the slides and ladies, are moved "onto the arms 15 of the'slide 16, which is mount edin suitable guides 17 on the vertically i'novableicarriage 1S ofthe elevating mechanism at thefurnace ends'of the upper and lower frames 7 and 8.. \Vhile any suitable- 1; which rests on the upper frame 7, is properly charged. As soon as this ladle has receivedthe proper quantity of glass, the

pusher 20 at the upper end of the elevat-' ing mechanism is operated to so shift the slide 16 as to move the ladle toward the stream of glass. During the latter portion of the movement the ladle is'also turned toward receptive position. By these combined horizontal and turning movemen/ts the advancing edge, of the ladle is moved across the line of flow of the glass, as shown in Fig. 5, and thereafter the glass will flow' into the second ladle. The strand a of glass extending from the charged ladle to the second ladle is severed by any suitable shearupper frame 1.

ing means or may be ruptured by the movement of the charged ladle along the upper frame 7 toward the molds. Assoon as the second ladle has been moved as described to intercept the stream of glass the carnage of the charged ladle will be engaged by the chain 9 and moved along the upper frame to operative relation to one of the molds, into which portion of the glass is charged in the manner set forth in the application referred to. While the pusher 20 may be operated by any suitable means, it is preferred to move it by a crank arm 21,'on the shaft which is provided at its lowerend with a srazoucgl crank arm 23 provided with a roller extending into a cam groove in a rotating drum 2st as shown in Fig. 1. As soon as the charged ladle has been shifted along the upper frame 7}, as stated, the Poem-- her 18 of the elevator is lowered to place the ladle carriage 5 on the guide ways oi'thc As the member 18 49021- frame-;;.. ladle re'achesoperative relation to the proper tiniiesiits. downward movement after the 26,:jwherebvthe slide 16 is moved back in the gnides 17 The iovenients of the carriages along the asarrested as soon as the proper mold, preferably raising'the slides 4 out of engagement with the hooks onthe chain 9, as described in application' erial No. 682,375. -As soon as the movement of the carriage is arrested the slides 4 and ladles are raised so as to immerse the lower endsof the molds in the glass contained in the ladies. The upward movement of the slides and ladles are preferably effected by fluid [pressure mechanism, as in the application above referred to. hen the glass is forced into-the molds by'pressure above that of the atmosphere, the movable members ofthe lifting mechanisms are protided with ladle inclosing basins 27. But when at-v mospheric pressure is employed to move the .glass the basins are omitted. In order that the slide and ladles may move uniformly,

the' lifting mechanisms have secured thereto stems 29 having them upper ends shaped to enter sockets in the legs 28 on the slides 4, as clearly shown in Fig. 4.. When the ladles and molds are brought into the relation necessary for the transfer-of the glass the ends of the molds will be approximately central of the ladle, and in order to insure clear glass beingcharged, it is preferred that-in filling the ladies the stream should enter the ladle at points or along lines outside of the center of the ladle, as

shown in Fig. .2. By thus causing the stream to enter the ladle eccentrically, the

strand 3 of glass when out or ruptured will drop into'the ladle outside of the portion of the glass entered by the end of the'mold.

Figs. 8 and 9 show diagrammatically modifications in the movements of a charged.

and empty'ladle relative to the stream of glass and also .to each other, whereby the empty ladle is placedin the line-0f flow of glass. In Fig. 8 the empty ladle is raised to a position intermediate the spout or outlet from the supply receptacle and the plane of movement of the charged ladies to operative relation to the molds. In this respect the cohstruction indicated in Fig. 8 is similar to that indicated in Figs. 1, 5 and 7. But in lieu of interposing the empty ladle between the sport and charged ladle by a rotaryand horizontalmomement, the empty ladle being in receptive position is caused to intersect the stream of glass by a horizontal movement only. In Fig. 9 the empty ladle is moved .into the lineof flow of the glass but below the ladle being charged, which is in position to be moved horizontally. ta operatire'rela-tion to thcrnold, As soon as such that the latter will .drop' into the'empty ladle below, which is then raisedto the plane w of movement of the ladles toward the molds.

Although the glass will he heatedto such a. temperature, that no detrimental cooling will probably cccin during the charging ofdition, it may under some conditions be cle ladle is charged it is moved meet-agate and out of the line of flow of the glassf'sc' 'a larlle andits movementto a mold, se-that the glass will reach the mold-1n proper consii'able to heat the glassin the ladle, espe- 'ciallyto soften any chilled skinwhich' may forin'hnits. surface. To this end one or more'stutable burners or other heating means are arranged in such position relative to the path, of the'ladles from charging'point to the molds, that heat of more or less intensity may be applied to the glass as shcwnin I claim" herein as my invention:
